This is my motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813130693

I currently have 8 GB of this RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233185

I would like to add only 4 GB more, but is it better to add 2x 2 GB sticks, or just 1 4 GB?

EDIT: Also, upon searching Newegg, there does not appear to be an EXACT match in 4 GB...is this OK? I can find DDR3 1600 (PC3 12800), but for 4 GB, the CAS Latency is different (either 7 or 9, not 8 like my current sticks).

No, that is fine. That's two different pairs. I like to have all the same but in all honesty my laptop has 4 different (similar) sticks and runs fine.

What I wouldn't do is add 1 2gb and 1,4 GB
Just check in the manual which sockets to use for each pair

By matched pairs, are you saying that it is bad to have a pair for 4 GB sticks, and then to add a pair of 2 GB sticks?
